Despite a U.N. resolution, President Obama's calls for an immediate ceasefire and the threat of international military intervention, forces led by Libyan dictator Muammar el-Qaddafi entered the rebel-held city of Benghazi on Saturday.

Qaddafi called the U.N. resolution, passed on Thursday, "invalid," according to the Associated Press, and he said he sent a letter to Obama and other leaders explaining his decision.

Obama is in Brazil as part of a planned trip there, and Secretary of State Hillary Clinton is in Paris with other world leaders to discuss how to coordinate the no-fly zone. The Security Council resolution authorizes the use of any force necessary to protect civilians, excluding the use of occupation forces.

"These terms are not subject to negotiation. If Qaddafi does not comply with the resolution, the international community will impose consequences. And the resolution will be enforced through military action," Obama said.
